By opting for this renewable, locally sourced, and environmentally friendly building material, you are positively impacting the planet while creating a comfortable and efficient living space. The inherent insulation properties of straw bales help to maintain a comfortable indoor temperature, reducing the need for heating and cooling systems. This energy efficiency not only minimizes your carbon footprint but can also lead to significant savings on utility bills. Straw bale houses are gaining popularity due to their eco-friendly and sustainable nature.

Straw bale houses are more susceptible to moisture-related problems since straw will decay and weaken if it becomes damp, which can quickly turn dangerous for inhabitants. Studies in Italy show that the embodied energy (the sum of all the energy required to produce the home) is about half that of a traditional home, while the CO2 equivalent emissions differ by over 40%. Straw bale houses are relatively rare, but the practice is picking up steam thanks to the growing sustainable design trends. People are often amazed at how the finish materials can add up and quickly. For example, consider that a light fixture at a big box store might cost $12, while a similar looking fixture made to much higher standards of quality could cost upwards of $250. Now multiply that by all of the light fixtures in your home and you will see why this is an important detail to manage from the start.

Essentially, there are two ways to build a straw bale house—load bearing and non-load bearing. A load-bearing straw bale house uses straw bales as the primary structural support, making it more reliable in milder climates. Entering the 1,850 SF home, you’ll find yourself drawn to the soft curves and warm nooks created by the deep straw bale walls. The passive solar design lets in the right amount of low winter sun, making the window seats an ideal nest to cozy in, sip tea and watch the snowfall.

Usually, the corners are interlocked from one direction to another to provide greater stability. However, if you’re new to using straw for construction, you may be curious about how it works.

Numerous studies have been conducted to test the flammability of straw bale houses. Oxygen barely enters between the straws thereby limiting any chance of triggering combustion. While straw bales can burn in certain circumstances such as during construction, it is undeniable that their flame retardant nature is a desirable feature. Straw bales are large bundles of straw or other plant material stacked in layers to form bale walls. This type of construction has been around for centuries but has recently gained popularity among sustainability-minded individuals because it uses natural, locally-sourced, renewable materials. Although some people might find the idea of a straw bale house dubious, it’s actually quite durable and sturdy.

Additionally, the walls need periodic maintenance, such as re-cementing or replacing sections of damaged plaster every few years to keep them in good condition. Each year, some 200 million tons of straw are burned in the U.S., adding to the already dangerously high concentration of carbon dioxide in the atmosphere. Straw bale construction sequesters some of the carbon released by burning, thus helping reduce global warming.

Straw bale houses are considered eco-friendly thanks to the main material, straw, being a completely renewable byproduct of the agricultural industry. Additionally, small sections of the interior wall may be left unplastered and opened with a glaze or frame like a window so occupants can see what the straw building looks like inside. This vegan flavor was created in collaboration with Renewal Mill, an upcycled food company that turns nutritious byproducts from food manufacturing into superfood ingredients and premium, plant-based desserts. It features chewy caramel-frosted chocolate brownies churned into a sweet oat milk base. The most common size of the plans is Architectural D or 36″x24″; however, we do sell plans in other sizes. The driving factor of the plan size is the scale of the drawings and the size of the structure.

Additionally, straw may attract pests like rodents, requiring adequate measures to deter them. Another potential drawback is the limited availability of skilled builders experienced in straw bale construction, which could increase costs or limit your options. These challenges aside, straw bale houses are a affordable, environmentally-friendly, and unique alternative to standard building practices. It is a home you can build for yourself that will stand the test of time without harming the environment around it.
